CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 357,957, dated February 15, 1887.

Application filed December .22, 1856. Serial No. 222,288. (No model.)

To all whom, it may concern.-

Be it known that I, SAMUEL FREAMAN GREEN, a citizen of the United States, residing at Salamanca, in the county of Cattaraugus and State of New York, have invented certain new and useful Improvements in Car- Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of carcouplers in which the coupling is automatic or self-coupling; and it has for its object to produce a coupler which can be easily and safely uncoupled with-out entering between the cars, and therefore without risk to life or limb, and which will be simple of construction, cheap to manufacture, and durable; and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of my device attached to the end of a car; Fig. 2, a plan View of the coupling proper; and Fig. 3, a longitudinal section, on an enlarged scale, of one of the jaws of the coupler.

Similar letters refer to similar parts throughout the several views.

A represents the draw-heads of the coupler, one of which is placed under and at each end of the car and there secured in a manner which will be described, so that a part thereof will project beyond the end of the car, as shown in .Fig. 1. These draw-heads consist of spring-metal bars,which are divided or slotted longitudinally nearly their whole length, and which are slightly enlarged at their outer ends, where the jaws a a are formed. The jaws a are cut away on each side to form arrowheaded projections b, while the jaws a are cut away on their inner side only to form hookshaped projections b, and thus form between the jaws the heartshaped opening 0, which receives the arrow-headed projection b when the two heads are brought together, said projection b forcing the jaws apart until its points slip past the points'of the opening, when the jaws close and hold the projections securely in place. In the projections b a perforation or opening, 9, and two or more slots, 9, are

on it meets a car having merely the link-and pin coupling they may be coupled by inserting the link in one of the slots and passing a pin through the perforation. The jaws will be made sufficiently wide to couple cars of different height.

B is a block in which the draw-heads are hung on a bolt, I), passing through their rear ends. The blocks B are secured in any desired manner under the cars, near or at each end, and are slotted to, receive the heads A, and a socket or recess, 6, is also formed in them immediately in the rear of the ends of the heads. This socket extends some distance back into the block, and permits the play or free movement up and down of a rod, g, secured in the rear end of the heads.

G is a lever pivotally attached to the drawheads at one end and to a lever, D, atits other end, said lever D being pivotally attached to the end of the car at about its center. The levers are duplicated on the opposite side of the car; but the ratchet is not, asitis only needed on one side.

E is a hook or ratchet fastened to the side of the car at its end.

F is a coiled spring, one end of which is secured to that end of the lever nearest the hook, and has its other end suitably secured to the car beneath the lever. This spring will be strong enough to raise the head A. 1

Thus it will be seen that upon releasing the lever D from the ratchet or hook E and lifting the lever up the head A will be permitted to drop down, and thus release the projection b from the opposite head or jaws, thus uncoupling the cars, while the rod g will prevent it dropping down too far, the recess 6 only giving sufficient play to said rod, so as to permit the projection to clear the opposite jaws. After the cars are uncoupled the spring F will raise the head again to its operative position, and, in connection with the ratchet, hold it ready to be coupled.

YVith this coupler it makes no difference which end of the car is backed up, as the parts of the coupler on each end of the'car are similar.

Having thus described my invention, what formed, so that when a car having my coupler I claim as new, and desire to secure by Letters Patent, is-
